ROAD-GRADER.

Patented June 8, 1915.

Application filed August 29, 1912, Seria1 No. 717,712. Renewed July 14, 1913. Serial No. 779,005.

To all whom it mayconcern:

Be itknown that I, HUGH citizen of' the United States, residing at upon its support.

Buhl, in the county of Twin Falls and State of Idaho, have invented a new and useful Improvement in Road-Graders, of which the following, is a specification. I

The object of my invention is to provide a road grader which is adapted to be mounted upon an axle or other suitable supporting part of a'vehicle and which can be detached at will. It is desirable that a grader of this character shall be inexpensive, simple, adjustable, and effective in operation and also adapted for use on either side of a road. These features are accomplished by my invention in an efficient and effective manner and the device is adapted to improve the condition of the road so that chuck holes are not formed, the road being kept smooth and oval in shape. I

In the accompanying drawing I forming part of this specification Figure l is a plan of the running gear of a wagon showing myimproved grader applied thereto; Fig. 2 is a side elevation and Figs. 3 and 4c are details showing the construction by which the disk may be held in selected position In the drawings A indicates the running gear of a wagon having a front axle 2, back .axle'3 and wheels 4, said front axle being mounted upon king bolt 5 so as to turn freely below the front bolster 6.

B indicates my improved grader which has a drag G and an earth working device D in the form of a disk in advance of the drag, said parts being adapted to cooperate and level the surface of the .road over the track on the wheels on either side of the running gear. I

A frame is provided-upon which the drag or scraper and disk are carried, said frame being of triangular shape and formed by two arms 7 and 8, said arms forming two sides of a triangle with the apex thereof directed rearwardly from the front axle '2. The ends of the'arms 7 and 8 are detachably hinged by bolts 9 and 10 to the axle 2 and the arm 7 is a tube into which an extension rodll is adapted to telescope to provide extensible adjustability forv the drag and disk G. TAYLOR, a

as regards the frame which carries them. Any suitable means may be employed for detaclhably securing the arms 7 and 8. to the ax e.

The extension rod 11 is held in the tube 7 by split pins 12 passing transversely through said parts, said pins also serving to prevent rod 11 from turning in its support. Upon the end of arm 11 a disk D is mounted by means of a. short shaft 13 which is journaled to the disk and adjustably secured to the end of the arm 11 .by means of the bolt 14L passing vertically through enlarged horizontal flat portions on. the adjacent ends of rod 11 and shaft 13. The impinging surfaces upon said enlarged portions of the ends of the extension rod 11 and shaft 13 are serrated at 15 so that when the bolt 14 is tightened by its lock nuts the shaft 13 is held rigidly in radially adjusted posi-.

tion. This radial adjustability ofthe disk allows the disk to be set while in upright position at any angle desired across the surface of the road to produce the desired width of cut. The disk is also held in longitudinally selected position upon the shaft 13 between collars 16 which are secured to said shaft by set bolts-l7. Thusgreater range of adjustability is provided for the disk whereby it may be so placed over that portion of the road as to most efiectively loosen and direct the loosened earth inwardly and upwardly over the road surface. The extensible rod 11 also carries a pair of rearwardly extending supports 18 upon which the drag C is rigidly mounted, said drag consisting of a vertically disposed plate 19 extending back from the disk and inclining rearwardly trated passing over sheaves 24: on the side of the body 25 of the vehicle and their links fastened to hooks 26 on the body. To hold the frameB and drag insuperior position t 7 is onlynecessary to draw the chains forward and secure their links over the hooksp- By mounting the frame supporting the disk and scraper on the front axle the 'device is made to follow in the track ofone of the front wheels around curves.

use either on the right or left hand side of direction. The parts are made of sufiicient weight to urge the earth working device and scraper effective engagement with Should either the'scraper or disk meet with an obstruction it will mount and ride over it independent of theother. The entire device may be quickly and easily attached to or detached from the front axle. It is further obvious that the device may be fastened in i have described the principles ofloperation of myinvention together with the apparatus Which I now consider'to represent the best embodiment thereof but I desire" to have it understood that the. construction shown is only illustrative and that the invention can be carried out by other means and applied to uses other than those-above set forth within the scopejof. the following claims.
